Sewer access points

Sewer manholes are access points to Council’s sewer mains and are used to check the condition of sewers, clear blockages in sewer lines and provide access to investigate and rectify infiltration.

We conduct routine manhole inspections to ensure they:

• Are accessible and visible;
• Do not leak or have stormwater directed into them; and
• Do not contain tree roots or blockages.

If a manhole within your property is not accessible, Council may direct you to make it accessible or do work on your behalf. In some instances, excavation may be required. For example, if a garden bed has been built over the manhole, Council may direct the property owner to remove it to restore access.

Can I adjust a manhole because of works on my property?

We understand that at times property owners, builders, or developers may require a manhole to be raised or lowered due to works going on within a property.

On application, a manhole adjustment will be assessed and if approved, will be undertaken by Shoalhaven Water free of charge.

A boundary riser is an access point to your property's sewer system. It's typically located near the property boundary where your internal plumbing connects to the council's sewer main. Your boundary riser must have a watertight lid, and easy to locate. The riser provides access for inspection, cleaning, and maintenance of the sewer connection. 

A boundary riser typically consists of a vertical shaft covered with a cap or lid. It is the property owner's responsible for maintaining safe access to the boundary riser, including the lid.

If you suspect a blockage, call us so that we will investigate Council's sewer main and clear any blockages that may be present. If the blockage is on your side, we will recommend you call a plumber. 

A yard gully (sometimes known as an overflow relief gully) is drain-like in appearance and located outside your house often near the kitchen or laundry. It's a vital part of your sewer system designed to prevent sewage from backing up into your home during blockages or when the sewer system is overloaded. 

It's typically installed outdoors, at the lowest point in your home's sewer system, below the lowest connected drain like a shower or floor waste gully. If a blockage occurs in your sewer line, the grate will pop off, allowing sewage to overflow to the outside, preventing it from backing up into your home. 

Regular inspection of the yard gully is crucial to ensure it's clear and functioning properly. 

The yard gully is designed to protect your home from the unpleasant consequences of sewer overflows. A yard gully generally looks like this:
